CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority under 35 USC § 119(e) to U.S.Provisional Application Ser. No. 63/473,460, entitled “Segregated multifluid pump head assembly”, filed May 31, 2022, the disclosure of whichis incorporated by reference herein.

BACKGROUND OF THE INVENTION

Heretofore, high pressure plunger pumps pumped one fluid at a time.Generally, a two step cleaning system with two solutions and highpressure rinse on demand and under pressure typically include threeindividual high pressure pumps, three pump frames, three drive motors,six pulleys and drive belts. This invention eliminates the need for mostof these components. The present invention will provide two highpressure cleaning solutions and high pressure rinse configuration withonly one pump and one drive motor.

BRIEF SUMMARY OF THE INVENTION

This invention relates to high pressure plunger or piston pumps, and itparticularly relates to the pressure head assembly wherein the head issegregated allowing more than one fluid to be pressurized and dischargedindividually of other high pressure fluid discharged from head assembly.

BRIEF DESCRIPTION OF INVENTION

It is one objective of the present invention to overcome the limitationsof one fluid at a time from an individual pump by providing a highpressure pump wherein multiple sources of different fluids areselectively connected directly to the segregated head assemblyindividual of other fluids.

It is the objective of the present invention to simplify production andreduce manufacturing cost of multi fluid cleaning systems.

Another objective of the present invention is to provide a head assemblyfor plunger pumps that can source the aforesaid type which is relativelysimple in construction and operation and relatively inexpensive tomanufacture.

DETAILED DESCRIPTION OF THE INVENTION

The objectives and many of the attendant advantages of this inventionwill be readily appreciated as the same becomes better understood byreference to the following description when read in conjunction with theaccompany drawings, Wherein:

FIG. 1 : Front view of two plunger high pressure segregated headassembly. 1. Illustrates partitioned segregated head assembly 100embodying a first embodiment of the present invention. 2. Referencenumbers one (1) and two (2) are shown only to illustrate the generallocation of plungers in commonly used two plunger high pressure pumps.

FIG. 2 : Front view of a two chamber segregated head assembly 100 thatprovides two individually sourced fluids entirely individual of oneanother from respective tanks 8, 9 to desired application apparatus(such as a spray nozzle not shown) using a single high pressure pump.

Referring in greater detail to the drawing of FIG. 2 , the head assemblydesignated 100 comprises a partitioned segregated head assembly creatinga separate pressure chamber for each plunger 10. From tank 9 fluid flowsthrough conduit 7 and into check valve 3A, wherein fluid is pressurizedand discharged through check valve 2A under high pressure fluid flowsthrough conduit 5 and out to the application apparatus. From tank 8fluid flows through conduit 6 and into inlet check valve 3B whereinfluid is pressurized and discharged through check valve 2B under highpressure flows through conduit 4 and out to the application apparatus.

FIG. 3 : Front view of a five plunger high pressure head assembly200. 1. Illustrates partitioned segregated head assembly embodying asecond embodiment of the present invention illustrating three segregatedchambers. 2. Numbers twenty-one (21), twenty-two (22), twenty-three(23), twenty-four (24) and twenty-five (25) are shown only to illustratethe general location of plungers in common high pressure plunger pumps.

FIG. 4 : Front view of a three chamber configuration segregated headassembly. This configuration is joining three plungers for one chamberproviding high pressure rinse. The remaining two plungers are segregatedfrom one another and provide two individual solutions. Numberstwenty-one (21), twenty-two (22), twenty-three (23), twenty-four (24)and twenty-five (25) are shown only to illustrate the general locationof plungers in common high pressure plunger pumps.

Referring in greater detail to the drawings of FIGS. 4 and 5 , the headassembly designated 200 comprises a partitioned segregated head assemblyconfigured to provide three separate pressure chambers. Lines 2210 and2220 designate separation between the three pressure chambers C1, C2 andC3. In this configuration there are five plungers designated 21, 22, 23,24 and 25 making up three pressure chambers C1, C2 and C3 wherein threeplungers 21, 22, 23 are segregated and joined by a manifold 208therefore combining their respective volumes of fluid to provide onehigh volume and high pressure rinse. The remaining two plungers 24 and25 are segregated from one another as denoted by lines 2210 and 2220 andprovide two high pressure solutions completely individual of one anotherfrom respective tanks to desired application apparatus.

In operation, fluid from tank 214 flows through conduit 209 to inletmanifold 208 joining inlet check valves 203A, 203B, 203C wherein fluidis pressurized and discharged out the discharge check valves 202A, 202B,202C respectively and joined by manifold 207 then out through conduit206 to desired application apparatus. Simultaneously fluid from tank 213flows through conduit 210 to inlet check valve 203D wherein fluid ispressurized then discharged out the discharge check valve 202D throughconduit 205 then out to desired application apparatus. Simultaneouslyfrom tank 212 fluid flows through conduit 211 to inlet check valve 203Ewherein fluid is pressurized and discharged out the discharge checkvalve 202E out through conduit 204 then out to desired applicationapparatus. Conduits 204, 205, 206, 209, 210, 211 are not of any specificshape or material. A single high pressure pump is operatively connectedto the segregated head assembly and check valves 202D, 202E, and 202A,202B and 202A are individually actuated to direct selected fluid to thedesired application apparatus.
